Keysight 84907L Attn,70dB,10dB stps, 40GHz, Programmable

Manufacturer: Keysight

The Keysight 84907L programmable step attenuator sets new standards for size and performance. It offers coaxial measurements to 40 GHz in a compact, rugged design, repeatability better than 0.03 dB, excellent life (greater than 5 million switching cycles per section), and an attenuation range of 0 to 70 dB in 10 dB steps. Keysight achieved high attenuation accuracy and low SWR with miniature thin-film attenuation cards composed of high-stability tantalum nitride film of sapphire substrate. Get outstanding insertion loss — 2.4 dB at 40 GHz from a unit that's 35 percent smaller than the Keysight 8495/7 26.5 GHz) family for easy integration into instruments and ATE systems.
